UMMC ER-IHC Breast Histopathology Whole Slide Image and Allred Score

This database contains 37 estrogen receptor immunohistochemistry (ER-IHC) whole slide images (WSIs) obtained from Universiti Malaya Medical Centre (UMMC), Malaysia. The WSI is scanned using 3DHistech Pannoramic DESK at 20x magnification with an approximate dimension of 80,000 pixels width and 200,000 pixels height per WSI. These 37 WSIs have Allred scoring by the collaborating pathologists with a breakdown of 17 ER-negative (4 score of 0; 13 score of 2), and 20 ER-positive (12 score of 3; 5 score of 7; 3 score of 8) with regions annotated by the pathologist to assist computational method in obtaining Allred scores. Image name with related score is listed in Table 5 of our paper, and the WSI annotations (referred as ROI-WSI) are included in this database using WKT format (POLYGON ((x1 y1, x2 y2, x3 y3, ..., xn yn, x1 y1))).
